Objective: A seismic measurement of rotation requires the detection and an accurate measurement of rotational splittings. Our ability to achieve this goal with current and forthcoming observations depends on the properties of the target star ( i.e. spectral type and distance) and will be discussed. Method: theoretical computations of solar- like oscillation amplitudes , amplitude threshold detection, and estimation of frequency- measure ment accuracy Results: Three levels of detection and measurement accuracy according to the type of star are obtained. They correspond respectively to: i) determination of the surface rotation period only, ii) enough rotational splittings can be detected and accurately measured allowing forward techniques iii ) enough rotational splittings can be detected and accurately measured allowing inverse techniques to obtain information on the rotation profile of the star. As an illustration, results from a " hare and hound" exercise carried out by the CoRoT team will be presented.
